Outline of Final Research Achievements

Regional myocardial rotational motion analyzed with cine MRI by following up the track of characteristic points on the intimal or the epicardial surface of left ventricle was almost equivalent to that with myocardial tagging images by following up the track of the intersections of grid-like tags on the left ventricular myocardium. Individual differences of longitudinal regional myocardial motion made it difficult to expand 2D motion analysis analyses to 3D ones. 2D regional myocardial motion analysis of patients with pulmonary hypertension demonstrated the presence of reduced regional myocardial motion segments even in the cases with normal global left ventricular motion.
